History
In ancient times, Kasos, Astrabe was used as a safe harbor by the Philistines. The first known settlements are Minoan and Mycenaean in origin. According to Homer, Kasos contributed ships toward the Trojan War. During Classical Antiquity it closely followed the history of nearby Karpathos. It was a member of the Delian League. Along with Karpathos, it was subjected from 1306 until 1537 to the VenetianCornaro family, then belonged to the Ottoman Empire. Kasos took part to the Greek Revolution and supported the cause with its fleet. In 1824, Mehmet Ali Pasha of Egypt, furious with the Kasiots, dispatched his fleet to the island : the Egyptian armada plundered the island, killed 500 people and enslaved 2000, an event described as Kasos massacre. The island's population recovered as did its economy, still largely based on shipping. The introduction of steam ships made Kasos' shipyard redundant and its economy suffered accordingly. Beginning in the later half of the 19th century, many emigrated from Kasos, initially to Egypt, then to Istanbul, Greece, USA and South Africa. By the 1920s, out of about 2,300 houses on the island, only 400 were permanently inhabited. On 12 May 1912, during the Italo-Turkish War of 1911-12, after the so-called "Battle of Cassos" which took place on 29 January 1912, the island was occupied by the sailors of the Regia Marina ship Regina Elena. With the Treaty of Lausanne of 1923, Kasos joined the other islands of the Dodecanese in the Italian possession of the Italian Aegean Islands, and was ceded by Italy to Greece with the Paris Peace Treaties of 1947. The island formally joined the Kingdom of Greece on 7 March 1948 together with the other Dodecanese islands.
